Loading the FRITZ!Box factory settings

When you load the factory settings, all of the individual settings you made in the FRITZ!Box are deleted. It makes sense to load the factory settings if you are going to use the FRITZ!Box at a different location or are planning to pass the FRITZ!Box on to another user, for example. In addition, this deletes incorrect settings that prevent the FRITZ!Box from functioning properly.

You can either use the user interface or a telephone connected to the FRITZ!Box to load the factory settings.

Note:The configuration procedure and notes on functions given in this guide refer to the latest FRITZ!OS for your FRITZ!Box.

2 Loading factory settings with a telephone

You cannot use an IP telephone, for example FRITZ!App Fon, to send key commands to the FRITZ!Box; you therefore cannot use IP telephones to load the factory settings:

Configuring a telephone to use the keypad function

Keypad sequences are strings of characters and digits that can be used to enable or disable functions. You can use keypad sequences right away with telephones, such as FRITZ!Fon C5, that are registered with the base station of your FRITZ!Box. If you are using a telephone connected to the "FON S0" port or a cordless telephone that is not registered with the FRITZ!Box's base station, you must first set up the keypad function:

Configure the telephone so that you can send keypad sequences (sequences of symbols and digits, such as *121#) and enter special characters such as * and # with them. With many telephones, you can use the menu "Operation at a PBX > Dialing options > Dial * and #" to configure this.

Loading the factory settings

Enter #991*15901590* on your telephone and press the call key (lift the receiver).
